May 17, 1938- J, F. oMALLEY SAFETY RZOR Filed Aug. 5, 1936 ATTORNEYSilNvENTOR ms EQ Inu WlTN ESSES CIJ Patented May Y17, 1938 UNITED STATESPATENT oFFlcE 1 Claim.

This invention relates to safety razors, an object of the inventionbeing to provide a safety razor having an improved construction andarrangement of guard and cap constituting clamping means for a doubleedged safety razor blade between them, said parts being capable ofadjustment so as to accommodate various thicknesses of blade and permitexing of a thin blade and securely clamping a rigid blade withoutilexing the same.

Another object is to provide an improved construction of guard and capwhich insures a proper positioning of the blade and the retention ofsaid blade in proper position under all conditions.

A further object is to provide a safety razor of this character whichcan be readily taken apart, thoroughly cleaned and reassembled.

With these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, all of which will be more fully hereinafter described and pointedout in the claim.

In the accompanying drawing- Figure 1 is a View in side elevation of myimproved safety razor with the parts assembled for use;

Fig. 2 is a view in transverse section through the center of the head ofthe razor and a portion of the handle, the rest of the handle beingshown in elevation;

Fig. 3 is a top plan view of the razor shown in Fig. 1;

Fig. 4 is a view in longitudinal section through the center of the headof the razor;

Fig. 5 is a perspective View of the razor cap;

Fig. 6 is a plan View of the bla-de;

Fig. 7 is a perspective view of the guard;

Fig. 8 is a view similar to Fig. 2 showing the position of the cap andguard with a rigid or non-flexible blade clamped between them.

My improved safety razor comprises three main parts, namely, a guard I,a cap 2, and a handle 3. 4 represents a double edged safety razor bladeclamped between the cap 2 and guard I, and said cap is formed centrallywith a screwthreaded stud 5 which projects through openings 6 in theblade 4 and through an opening I in the guard I and engages internalscrew threads 8 in the tubular handle 3 so that when the handle isscrewed tightly against the guard the cap 2 will be drawn downward tosecurely clamp the blade 4 between the cap and the guard. While I employthe terms cap and guard to indicate the parts of the razor head such ascommonly employed in the art, it is to be noted that as a matter of factboth the members I and 2 constitute guards as they are provided alongtheir longitudinal edges with teeth 9.

The guard I is formed on its upper face at 5 both ends with a pair ofspaced lugs IU, and extending from these lugs to the side edges of theguard are transversely extending webs II, and between the lugs I Il atthe extreme ends of the guard, recesses I2 are formed in the guard. Thecap 2 is provided in its ends with spaced recesses I3 to receive thelugs Ill, and between these recesses I3 longitudinally extending bars I4are provided which extend beyond the ends of the cap and at theirextremities are provided with downwardly extending fingers I5 which areadapted to be positioned in the recesses I2 in the guard. The blade 4 isof the double edged type and is provided in its ends with spacedrecesses I6 which receive the lugs I0 of the guard, and the blade is ofsuch a length that it i'its nicely between the webs II at the ends ofthe guard. In other words, the blade is coniined and held againstlateral or longitudinal movement relative to the guard and cap'by reasonof the fact that the lugs I0 project through the recesses I6 of theblade and the webs II conne the ends of the blade and, furthermore, whenthe cap is screwed down tightly upon the blade its bars I4 and fingersI5 resting in the recesses I2 further confine the ends of the blade sothat the blade is incapable of displacement from its normal properposition relative to the guard and cap when the parts are properlyassembled.

The blade 4 must of course have a central opening 6, as above dened, toreceive the stud 5 of the guard, and where the blade is a exible one inaddition to this opening 6, longitudinal slots I'I are formed centrallyof the blade and merging into the opening 6. It is to be understood, asabove stated, that my improved razor is adapted to clamp not only aflexible type of blade, which is given an arched ilexed formationbetween the cap and guard as shown most clearly in Fig. 2 of thedrawing, but it is also within theV scope of the invention to provide arigid or nonflexing blade which is also securely clamped between the capand guard as shown in Fig. 8 of the drawing.

While I have illustrated and described what I believe to be thepreferred embodiment of my invention, it is obvious that various slightchanges may be made with regardto the form and arrangement of partswithout departing from my invention, and hence I do not limit myself tothe precise details set forth but consider myself at liberty to makesuch changes and alterations as fairly fall Within the spirit and scopeof the claim.

I claim:

A razor head including a cap and a guard adapted to clamp a bladebetween them, spaced lugs integral with the guard at the centralportions of both ends thereof, webs extending from the lugs to the sidesof the guard, the surface between the lugs being flush with the surfaceof the guard, the blade and the cap both having recesses in their endsto receive the webs, integral bars at the ends of the cap between therecesses therein, said bars extending beyond the ends of the cap andadapted to rest between the lugs on the guard, fingers at the ends ofthe bars adapted to overlie the ends of the blade between the cap andguard, said guard having recesses in its ends receiving the fingers.
